You can connect the separate receiving antenna to the K3 internal 144 MHz
xverter by using the P3 AUX 144 MHz IN 3 pin connector.
use pin 2 (RF) and pin 3 (ground). This by-passes the K144XV input and diode

what I use.

I would say it's hard to beat success like you have had with the Astron

You should also consider a 35 to 55 AH (or thereabouts) Gel-Cell battery
and a 3 to 4 amp automatic charger. Advantages: (1) Instant emergency
power good for several hours, (2) protection against line spikes

If the Astron is toast, it's a pretty simple circuit to repair (if parts
can be found). I'd either fix it or replace it with one from the same

Hi Bill,
Last year I replaced a decade old Astron SS-20 (field day 2011 death)
with a new SS-25. I prefer a quiet room and use the rig speaker. The new
SS-25 fan is too noisy, even hidden under the desk, for me. Much louder
then the K3/100 fan.
My plan is to try a Samlex 1223 or 1235 next.
This has been covered several times ...
Are the 20 amp supplies enough power for the K3?
They are marginal - I have seen 22A or slightly more with some
loads on some bands. Given that the current metering is somewhat
an average, the instantaneous peaks will be higher. 25A is a
realistic
Some of the instructions in the K2 manual are not precise to the point.
It could easily be adjusted.

The oldest doesn't have meter lights. The 2 newer ones do.
They run the rigs just fine. I do not have any fan noise.

There are very few places to check resistance. You should find a high
resistance at all pins of the LM386 (except perhaps pin 6 which is the
voltage rail and pin 4 which is ground.
Note that all other pins have a capacitor and that will stop DC
